Possible reasons for my MacBook Pro restart randomly

Hi everyone i was just normally using my mac for work then i finished and put it to sleep but a few minutes after screen boots up and it says ''Your computer was restarted because of a problem" but it did not state what the problem was. Is there a way to find out what the reason of this reboot was?

I've never seen this type of Kernel Panic before. It seems "PAC" refers to Pointer Allocation Code which is meant to protect against exploitation of memory corruption bugs. Here is an Apple article which mentions it & other security measures built into macOS:

I recommend posting the complete EtreCheck report so we can examine it for possible clues to possible software issues which could cause this panic. If we don't see anything, then it would be more likely to be a hardware issue.


You can also try running the Apple Diagnostics to see if any hardware issues are detected. However, only a failing diagnostic will be useful since a passing diagnostic is meaningless.

Thanks for your time. What does the first part mean? Is it necessary to post the rest of the report? Apple diagnostic did not find any major problem and i would hope is not something hardware related as the mac is 5 months old. Posted the EtreCheck report. I will add that i cannot have system updates on as a lot of music plugins I use might not be updated as frequently.

More than likely it was a Kernel Panic. See if any Kernel Panics logs exist in "/Library/Logs/DiagnosticReports". Most Kernel Panic logs will have file names with "kernel" and/or "panic" in the name. If none are in this folder, then check the "Retired" subfolder. Post several of the Kernel Panic logs here just as you did for the other System Log file.


FYI, except for the Kernel Panic logs, most of the other macOS system logs are worthless for troubleshooting these days. Plus the only way to actually get those other logs is with the command line...again they are mostly worthless for troubleshooting.


You can also run the third party app EtreCheck and post the complete report here so we can examine it for possible clues especially if third party software may be at fault. This report also includes summaries of the system logs as well.
